usb port not any longer recognized

I have installed 09.04 image and run

opkg install angstrom-x11vnc-xinit
reboot

But after the reboot I get

root@beaglebone:~# ifconfig
eth0 Link encap:Ethernet HWaddr 90:59:AF:5C:F9:9D

root@beaglebone:~# ifconfig usb0 192.168.7.2
ifconfig: SIOCSIFADDR: No such device
root@beaglebone:~# ls /dev/us*
/dev/usbmon0 /dev/usbmon1

Any idea how I get the usb back to working as 192.168.7.2?

I got the same problem, have you fixed it?
